IMMUNOGENICITY OF LOW-DOSE INTRAMUSCULAR AND INTRADERMAL VACCINATION WITH RECOMBINANT HEPATITIS B VACCINE

The study is a randomized trial using recombinant DNA vaccine to determine whether an intramuscular 10 µg dose or intradermal 2 µg induces satisfactory anti-HBs levels compared to the standard dose of intramuscular 20 µg. participants were 359 healthy medical and nurse students randomly allocated to one of the three groups: Group I - IM 20 µg; Group II - IM 10 µg; Group III - ID 2 µg at 0, 1 and 6 months. Anti-HBs titres were measured after complete vaccine schedule by ELISA/Pasteur. Baseline variables were similar among groups and side effects were mild after any dose. Vaccinees in the IM-10 µg group had seroconversion rate and geometric mean titre (GMT 2344 IU L-1), not significant different from the IM-20 µg group (GMT 4570 IU L-1). On the contrary, 21.4% of the ID - 2 µg recipients mount antibody concentration below 10 IU L1 and GMT of 91 IU L-1, a statiscally significant difference compared with the standard schedule IM-20 µg (p < 0.001). A three dose regimen of half dosse IM could be considered an appropriate schedule to prevent hepatitis B in young health adults which is of relevance to the expansion of hepatitis B vaccine programme

Os enfermeiros e as representações sociais sobre o envelhecimento : implicações nos cuidados promotores da autonomia da pessoa idosa hospitalizada

RESUMO: O envelhecimento da população tende a aumentar em todo o mundo, trazendo consequências a níveis sociais, económicos, e de saúde. As hospitalizações e a necessidade de cuidados de enfermagem à população idosa tendencialmente aumentam pela maior fragilidade, derivada do aumento das situações de doença crónica e dependência. Os cuidados de enfermagem podem ser influenciados pelas representações sociais acerca do envelhecimento, estando associados mitos e estereótipos, e levar à desvalorização da individualidade e autonomia da pessoa idosa. Neste sentido, preconiza-se a realização de cuidados em parceria com a pessoa idosa, que promovam a sua autonomia e empowerment. Este estudo tem como objectivo compreender o modo como as representações sociais dos enfermeiros acerca do envelhecimento influenciam os cuidados de enfermagem na promoção da autonomia do idoso hospitalizado. Realizámos um estudo qualitativo, com recurso à entrevista e a técnica por associação livre de ideias, sendo entrevistados 17 enfermeiros de um serviço de internamento de medicina. Da análise dos resultados, constatámos que para os enfermeiros do estudo a representação social negativa acerca do envelhecimento foi a mais evidenciada, associada a situações como: dependência, doença, solidão, isolamento, necessidades, tristeza, peso na sociedade/problemas/dificuldades; levando à desvalorização das capacidades físicas, mentais, psicológicas, e da autonomia da pessoa idosa. Como factores dificultadores da promoção do respeito e autonomia da pessoa idosa referiram a motivação, características do enfermeiro e da pessoa idosa e os constrangimentos institucionais. Contudo alguns enfermeiros utilizam estratégias facilitadoras da promoção da autonomia como a: apresentação, proximidade, disponibilidade, promoção da esperança, avaliação da situação, e capacitação física e mental. Concluímos que as representações sociais negativas acerca do envelhecimento condicionam os cuidados de enfermagem na promoção da participação da pessoa idosa nos cuidados e nas decisões relativas a si. Os cuidados realizados em parceria, influenciados por uma visão positiva da pessoa idosa, valorizam a sua individualidade e toda a sua história de vida fomentando a sua autonomia.---------- ABSTRACT: Population aging is a global phenomenon, felt particularly in developed countries, with consequences at the social, economic and health-related levels. Hospitalization rates and nursing care needs among the elderly are on the rise in part due to the increased fragility of this population which experience greater levels of dependency and chronic disease. The quality of nursing care may be influenced by social representations of aging, associated with myths and stereotypes, that may lead to the devaluation of the individuality and autonomy of elderly persons. To this end, advocates for care in partnership with the elderly person, that promote their empowerment and autonomy. The present study aims to understand the manner in which social representations held by nurses with regards to the phenomenon of aging influence nursing care, with particular emphasis on the promotion of autonomy among hospitalized elderly patients. This study is a qualitative study, utilizing interviews and the free association of ideas technique, with a total of 17 interviews conducted on nurses working in a hospital ward. According to our results, nurses harbour negative social representations concerning the aging process, associating the latter with dependency, disease, loneliness, needs, sadness, burden on society/problems/difficulties, all of which may lead to the devaluation of the physical, mental, and psychological capacities of the elderly, negatively impacting upon their autonomy. Among those factors found to hinder the promotion of respect and autonomy of the elderly in this study, are personal motivation, characteristics of the nurse and the elderly person and institutional barriers. However, some nurses made use of a number of strategies that promoted patient autonomy, namely: presentation, proximity, availability, the promotion of hope, situation evaluation and physical and mental capacitation. In conclusion, negative social representations concerning aging condition the quality of nursing care, particularly, in what concerns the promotion of patient participation in care and self determination. Nursing interventions carried out in collaboration with the patient, influenced by a positive view of the elderly, value the individuality and life history of these individuals, thereby fomenting their autonomy

Accidental tetanus: prognosis evaluation in a historical series at a hospital in Salvador, Bahia, Brazil

A total of 868 (84.89%) patients diagnosed with tetanus were studied, out of the 1,024 tetanus patients hospitalized at Couto Maia Hospital (Salvador, Bahia, Brazil), during the period between 1986 and 1997. Of this group (n = 868), 63.5% (n = 551) were discharged, 35.4% (n = 307) died, and 1.1% (n = 10) were transferred. The average age of the deceased patients (38.73 ± 23.31 years) was significantly greater (p < 0.0001) than the age of those who survived (29.21 ± 20.05 years). Analyzing the variables of the logistic regression model with statistic significance (p £ 0.25) for univariate analysis, we observed a greater association of risk for worst prognosis (death) in patients aged ³ 51 years; time of illness < 48 hours; time of incubation < 168 hours; neck rigidity; spasms; opisthotonos; body temperature ³ 37.7 ºC; heart beat ³ 111 beats/minute; sympathetic hyperactivity and association with pneumonia. Among the group of those who survived, patients with 1 to 5 of those variables (n = 398; 76.8%) were more frequent, while among patients of the group of the deceased, 70.3% (n = 206) presented 6 to 10 of those variables, with a highly significant difference (p < 10-8). In conclusion, the indicators described provide early information that may guide the prognosis and medical and nurse care.

Burnout dos enfermeiros nos serviços de saúde em Portugal : um estudo de caso na Saúde 24 Porto

RESUMO - A síndrome de burnout, definida pela exaustão emocional, despersonalização e realização pessoal, designa um estado de fadiga física e emocional crónico dos profissionais, o qual pode comprometer as organizações. Neste estudo descritivo, pretende-se estudar a síndrome de burnout nos enfermeiros dos serviços de saúde, especialmente focado nos serviços de atendimento permanente telefónico, suas características, consequências e estratégias de prevenção. A população alvo serão todos os enfermeiros que trabalham em serviços de atendimento permanente telefónico e a amostra, não probabilística e de conveniência, os enfermeiros que desempenham funções no centro de atendimento da Saúde 24 Porto. Primeiramente aborda-se o conceito de burnout e a sua relação com a prática de Enfermagem, de seguida é realizada uma descrição sobre os centros de atendimento em saúde até à atual situação da Saúde 24. Na amostra em estudo, enfermeiros da Saúde 24 Porto, existe predominância do sexo feminino (66,99%) e a média de idades é de 32 anos (26 anos de idade mínima, 49 de idade máxima e desvio padrão de 4,59). Constatou-se que 94,26% desempenha funções de enfermeiro comunicador e os restantes 5,74% são enfermeiros supervisores, a média de anos de atividade profissional é de 5,67 anos e 36,4% dos enfermeiros desempenha funções na Saúde 24 há mais de 3 anos. Foi aplicado o Inventário de Burnout de Maslach e os resultados indicaram a ausência de síndrome de esgotamento profissional. Existem níveis médios de burnout, sustentados pelos valores obtidos na exaustão emocional no terço inferior (<19,10), e valores no terço inferior, na realização pessoal (<38,00) e nível baixo na despersonalização (<4,90). No que concerne à idade não foram encontradas correlações significativas em nenhuma das dimensões, contudo, no que refere ao tempo de serviço verificou-se que existem correlações significativas e negativas para a exaustão emocional e para a despersonalização ou seja, a tendência atual é a de que os enfermeiros com menos tempo de serviço têm maior tendência para scores mais altos de burnout. Existe uma relação entre as variáveis, grau académico, exaustão e despersonalização, a qual mostrou uma tendência para scores mais altos em relação a enfermeiros licenciados e pós graduados nas dimensões de exaustão e despersonalização contrariamente aos enfermeiros com o grau de mestre ou especialidade. Existe também uma relação entre as variáveis género e despersonalização, sendo o score baixo, aquele que apresenta maior expressão no sexo masculino, mas principalmente no sexo feminino. As mulheres têm scores mais baixos que os homens nesta dimensão, traduzindo-se na percentagem mais elevada obtida (67,1%, contra 53,6%). E em contrapartida nos resultados obtidos para o score alto relativo à despersonalização, os homens apresentam um resultado pior do que as mulheres, sendo 26,1% para os homens e 12,1% para as mulheres. Quando se examinam as funções desempenhadas distribuídas pelas dimensões de burnout, verifica-se a existência de uma relação entre a variável função desempenhada e a realização pessoal. Nos resultados percebeu-se que, quanto mais elevada a função desempenhada (enfermeiro supervisor), mais baixa é a realização pessoal. E esta dimensão tem o score inverso, logo a interpretação deverá ser feita no sentido de que, quanto mais elevada for a função, maior será a realização pessoal. Os resultados obtidos são animadores contudo a vulnerabilidade para este tipo de problema, entre enfermeiros, potencializada pelo tipo de trabalho realizado por estes profissionais de saúde será desejável estar atento e usar estratégias para enfrentar o burnout quando ele surgir. O fenómeno burnout não é apenas como um problema do individuo mas é principalmente um problema da organização.

The Support Role in Clinical Supervision of Nursing Students: Determinant in the Development of Emotional Skills

The problematic situation faced by clients, associated to the processes of health and disease, is expressed through emotions that nursing students have to deal with in the course of care and their formative experiences in clinical teaching. Students have learning needs not only to manage emotions in the context of customer care, but also in terms of their own internal world, emotional conflicts, emotional stress and burn-out. With the present literature review, we intend to explore existing evidence regarding the ways in which the nurse supervisor's support towards nursing students potentiates the development of their competences for the performance of emotional labour. These skills prove to be the key in the ability to manage the emotionally intense situations of care practice and the support function of the nursing supervisor contributes to the development of such competences.

Who uses NHS saúde 24 hotline? Has the user changed over time?

There has been an increase in the use of telephone-based services and internet throughout the years and, therefore, the Saúde 24 Hotline has become an important service in Portugal. This service aims to screen, counsel and refer the patient in order to avoid unnecessary visits to health institutions and also to indicate the most appropriate resource according to the illness. This work has two different questions: the first one examines the determinants of satisfaction that have more influence on the overall satisfaction of the Saúde 24 Hotline users. The second one aims to analyze if the confidence level of the users is increasing over time, measured by following the recommendation. The first study was conducted on a random sample collected from June to October 2014, which was taken from the User Satisfaction Survey. The second approach includes data from January 2008 to December 2014 from the Clinical Data Base of all users who have called the Hotline. Findings suggest that the majority of users are very satisfied with the service and the variables with more impact on the overall satisfaction are commitment and availability from the nurse, adequacy of call duration and quick identification of the problem. The survey indicates that 94% of respondents follow the recommendation and on average people have called the hotline 3 times in the previous year. The results from the Clinical Database show that people who were recommended to go to the emergency room are more likely to follow the advice than the people who were recommended to book routine appointments

Exposição a radiações ionizantes em cirurgia ortopédica num hospital público de Lisboa.

RESUMO - A monitorização individual dos trabalhadores (dosimetria individual) é obrigatória (Decreto Regulamentar n.o 9/90, de 19 de Abril) para os profissionais de saúde que desempenham funções com risco de exposição à radiação X, quando classificados como categoria A. Apesar disso, a exposição a radiações ionizantes é frequentemente pouco, ou mesmo nada, valorizada pelos profissionais de saúde. O presente estudo, realizado no contexto de intervenções cirúrgicas de ortopedia, teve por objectivos: • avaliar a dose de radiação em diferentes zonas durante as cirurgias ortopédicas; • estimar a dose de exposição a radiações ionizantes dos profissionais de saúde, em função das suas posições, predominantemente adoptadas durante o acto cirúrgico; • sensibilizar os profissionais de saúde para a utilização correcta da dosimetria individual e para a adopção das medidas de protecção radiológica. A avaliação do risco foi efectuada através de: 1) medições preliminares com recurso a um fantoma colocado a 50 cm e a 100 cm do eixo central do feixe de radiação e em direcções de 45°, 90° e 135°; 2) medições durante uma cirurgia ortopédica em «localizações » correspondentes às gónadas, ao cristalino e às mãos dos profissionais de saúde intervenientes na cirurgia (ortopedistas, enfermeiros instrumentistas); 3) medições ao nível do topo da mesa (posição do anestesista) e ao nível do comando do equipamento emissor de raios X (técnico de radiologia); 4) determinação do tempo de utilização dos raios X durante as cirurgias ortopédicas; 5) cálculo da estimativa do número anual de cirurgias ortopédicas realizadas, com base nos registos existentes. Assumindo a não utilização de aventais plúmbeos os valores máximos medidos foram de 2,5 mSv/h (ao nível das gónadas), de 0,6 mSv/h ao nível do cristalino e de 1 mSv/ h ao nível das mãos dos ortopedistas e dos enfermeiros instrumentistas (que se situavam próximo do feixe de raios X, a 50 cm do feixe de radiação). A estimativa de exposição anual (dose equivalente) para os profissionais que operam junto ao feixe de radiação X foi de: • Ortopedistas — 20,63 a 68,75 mSv (gónadas), 4,95 a 16,50 mSv (cristalino) e 8,25 a 27,50 mSv (mãos); • Enfermeiros instrumentistas — 130,63 a 151,25 mSv (gónadas), 31,35 a 36,30 mSv (cristalino) e 52,25 a Os profissionais que ocupam posições mais afastadas do feixe (por exemplo: anestesistas) terão doses de radiação mais reduzidas, embora estas possam ainda ser importantes ao nível das gónadas na zona do topo da mesa (anestesista). Conclui-se que a exposição profissional em blocos operatórios pode implicar, em cirurgia ortopédica, a sujeição a níveis de exposição consideráveis, o que permite classificar estes profissionais de categoria A, justificando a utilização obrigatória (e correcta de acordo com as recomendações) da dosimetria individual e a adopção de medidas de protecção radiológica, tantas vezes negligenciadas.

Fathers’ emotional involvement with the neonate: impact of the umbilical cord cutting experience

Aims. This paper is a report on a study analysing the effect of the umbilical cord cutting experience on fathers’ emotional involvement with their infants. Background. Participation in childbirth offers an opportunity for father and mother to share the childbirth experience, so it is vital that midwives improve the fathers’ participation in this event. Design. A quasi-experimental study with a quantitative methodology was implemented. Methods. One hundred and five fathers were recruited as part of a convenience sample in a Maternity Public Hospital in a Metropolitan City in Portugal, between January and May of 2008. The Bonding Scale, the Portuguese version of the ‘Mother-to-Infant Bonding Scale’ was used to evaluate the fathers’ emotional involvement with the neonate at different moments: before childbirth, first day after childbirth and first month after childbirth. After childbirth, the fathers were divided into three separate groups depending on their umbilical cord cutting experience. Results. The results demonstrate that the emotional involvement between father and child tends to increase during the first days after childbirth and to decrease when evaluated 1 month after birth, for fathers who did not cut the umbilical cord. However, fathers who cut the umbilical cord demonstrate an improvement in emotional involvement 1 month later. Conclusion. Results suggest that the umbilical cord cutting experience benefits the father’s emotional involvement with the neonate, supporting the benefits of his participation and empowerment in childbirth.

Assessment of the techniques of blood pressure measurement by health professionals

OBJECTIVE: To assess blood pressure measurement by health professionals of a public hospital in São Paulo State. METHODS: Semi-structured interviews and direct observation were performed with a verification list according to the criteria reported by Perloff et al. One hundred and five health professionals took part in the study. After measuring blood pressure, the level of concordance between the way the procedure was performed and the recommended one was assessed. RESULTS: Nurses and nurse's aides abided by 40% of the recommended procedures for adequate blood pressure measurement. The other categories of health professionals (nursing and medicine teachers, physicians, residents, and nursing students) abided by approximately 70%. CONCLUSION: Permanent educational activities aiming at standardizing blood pressure measurement should be implemented among the different categories of health professionals.

Protein content and electrophoretic profile of fat body and ovary extracts from workers of Melipona quadrifasciata anthidioides (Hymenoptera, Meliponini)

Workers of Melipona quadrifasciata anthidioides (Lepeletier, 1836) develop their ovaries and lay eggs, therefore the production of vitellogenin is expected. In electrophoretic profiles only fat body extracts from nurse workers and ovary extracts from newly-emerged workers show protein with molecular mass similar to vitellogenin. However, an increase in the protein content was detected in forager fat body. This increase was attributed to storage of vitellogenin or other proteins in the previous phase and not discharged into the hemolymph or to an effect of the increased titre of juvenile hormone in this phase of worker life over the fat body functioning.

Morphological aspects of cell reabsorption in laying queens and workers of Apis mellifera (Hymenoptera, Apidae)

The occurrence of cell reabsorption in the ovaries of queens in several rates of laying eggs, artificially impeded of laying, and in nurse workers, of Apis mellifera (Linnaeus, 1758), was studied with light (LM) and transmission electron microscopy (TEM). Two types of structures were described and named by analogy with vertebrates ovarian structures, as corpus luteus, when resulting from the reabsorption of the follicular cells after ovulation, and corpus atresicus when resulting from total follicular reabsorption at any oocyte developmental stage. These structures have the same morphological characteristics and physiological signification in both castes. The corpus luteus occurrence indicates ovulation and its number is correspondent to the queen's rates of oviposition. The presence of this structure in nurse workers ovarioles shows that this caste may lay eggs. The incidence of corpus atresicus in queens decay with the increasing of the oviposition indicating that the inhibition of the normal sequence of oocyte maturation in the ovaries is deleterious. Both, corpus luteus and corpus atresicus incidence may be influenced by environmental factors.

Promoting hospital-based smoking cessation services at major Swiss hospitals: a before and after study.

Whether a 1-year nationwide, government supported programme is effective in significantly increasing the number of smoking cessation clinics at major Swiss hospitals as well as providing basic training for the staff running them. We conducted a baseline evaluation of hospital services for smoking cessation, hypertension, and obesity by web search and telephone contact followed by personal visits between October 2005 and January 2006 of 44 major public hospitals in the 26 cantons of Switzerland; we compared the number of active smoking cessation services and trained personnel between baseline to 1 year after starting the programme including a training workshop for doctors and nurses from all hospitals as well as two further follow-up visits. At base line 9 (21%) hospitals had active smoking cessation services, whereas 43 (98%) and 42 (96%) offered medical services for hypertension and obesity respectively. Hospital directors and heads of Internal Medicine of 43 hospitals were interested in offering some form of help to smokers provided they received outside support, primarily funding to get started or to continue. At two identical workshops, 100 health professionals (27 in Lausanne, 73 in Zurich) were trained for one day. After the programme, 22 (50%) hospitals had an active smoking cessation service staffed with at least 1 trained doctor and 1 nurse. A one-year, government-supported national intervention resulted in a substantial increase in the number of hospitals allocating trained staff and offering smoking cessation services to smokers. Compared to the offer for hypertension and obesity this offer is still insufficient.

Comparison of two osteoporotic fracture management pathways: experience at 1 year

Introduction: Osteoporosis presenting as low-impact fractures to traumatology units is often undiagnosed and under-treated. Results from the Osteocare study in Lausanne (a nurse based intervention, passive pathway) showed that only 19% of patients received management for osteoporosis, and in the literature [1], the rate is between 10-25%. We have evaluated a different management concept, based on the systematic assessment of patients with osteoporotic fractures during and after hospitalization (active pathway). Methods: Inpatients admitted to the Department of Musculoskeletal Medicine for a fragility fracture were identified by a nurse according to a predefined questionnaire and were then clinically evaluated by a doctor. Based on the results, a management plan was proposed to the patients. Patients could choose between follow up either by their GP or by the Centre of Bone Disease of the CHUV. For patients who chose follow-up in our Centre, we assessed their adherence to medical follow-up 1 year inclusion. The results of patients who had been evaluated in our cohort between the 1 November 2008 and the 1 December 2009 were analysed. Results: 573 inpatients received specific management of their osteoporotic fracture over 18 months. The mean age was 77 y (31-99), 81% were women (203 hip fractures, 40 pelvis fractures, 101 arm fractures, 57 vertebral fractures, 63 ankle fractures, and 25 others sites). During the study period, 303 patients received a proposition of a specific treatment. 39 (13%) chose a follow up with the GP, 19 (6%) dead and 245 (81%) preferred a follow up in our Centre. After 1 year, 166 (67%) patients are under follow up in our outpatient clinic. Conclusion: With an active clinical pathway that starts during the hospitalization, consisting on a nursing evaluation followed by a medical consultation by an expert in osteoporosis, the adherence increased from 19% to 67% in terms of follow up. These results lead us to propose a consultation with a doctor experienced in osteoporosis after all osteoporotic fractures.
